So the 2nd quest in the game where you get some flower and a root requires you to have the ingrediant skill.... How do you get this ?

Also do the radio's on the pip boy work in the beggining of the game ? Or is my game bugged ? I have 2 radio statiosn available but whe ni pick them nothing happens.. However i hear music in the buildings on those radio's

You don't need that skill. What you need to do is scroll down the left list until you find the words, healing powder, then combine the ingrediants on the right side of the list.

Check your game settings and make sure the radio volume is turned up.

To make healing powder you need survival skill.

I made the healing powder with 17 survival skill points. My character started with 9 intelligence and I didn't add any points to the survial skill, but I choose the good nature trait.
